STS Prepaid Meter: Smart Metering Core with IoT Data Gateway Integration

The STS prepaid meter is designed for decentralized deployment, featuring low-power consumption, wide voltage tolerance, and battery-backed memory for operation during grid interruptions.

International development programs and NGOs choose the STS prepaid meter for off-grid solar and micro-grid installations because the STS standard ensures interoperability across different meter manufacturers.

For project managers, a field-ready STS prepaid meter offers IP54-rated enclosures and large-character LCD displays readable in sunlight. A properly configured STS prepaid meter also supports multiple tariffs, including time-of-use and lifeline rates, adapting to various subsidy models used in rural energy access initiatives.
